look up any word, like bukkake:
 
1.
The polite interaction between two men with erections who are acknowledging each other's erections. This can also be used at random between two people, even without erections present. Women can also use boner etiquette.
Man 1: Hey, Todd, I noticed your boner there.
Man 2: Thanks, Johnny, I see yours too!
Man 1: Boner Etiquette is fun!

Woman 1: Hey Mary, I noticed your boner there.
Woman 2: Thanks, Karen, I see yours too!
